CONTAINER COVER Filed Oct. 1l, 1928 llllll lllllllllll Inventor f/271 0. grad/g By W v A ltorneyS Patented Dec. `v10, 1929 UNITEDy [STATES PATENT oFFxcn i .form (many, or mammalian, Lum l i i opnemen med october 1 1, 192s. serial No. 311,254.3.y

My invention relates to covers for containers and has for its object the provision of a device of the character designated which may be readily applied" and removed from the container without screwin the cover down and wherein the angular re ation of the cover and the container'may be readily changed.

A further objectof my inventlon is to provide a cover especially adapted for automobile radiators which usually carry an orna- 'ment of some character and which may be readily secured to and removed from the radiator without'screwing and wherein the angular relation of the ornament to the auto# mobile body may be readily adjusted.

A more specific object of my invention is to lprovide a fastening means for container covers which shall be readily attachable to and removable from the cover whereby a single size of fastener may be adapted `for a number of sizes of covers.v

Briefly, my invention comprises Aa flanged covertitting over the neck of the container, a plurality of inclined slots being provided in the neck. Yieldingly supported by the' cover is a spider having radially extending projections to fit into the slots and by means of which the cover is securedto the plate. The spider is secured to the cover in a man-l nerr permitting angular adjustment thereof, thereby providing means whereby the cover` is angularly adjustable with' respect to the container.

Apparatusembodying features of my invention is illustrated in the accompanying drawings, forminga part of this ap l ioation, whereinf Fig. 1 is a vertical sectional view of an automobile radiator'lcap having my improved fastening means; c

Fig. 2 is a. sectional view taken along the une n n of Fig. 1; and

Fig. 3'is a view similar to Fig. 1, but showing the cover removed.

Referring to th`e drawings for a better understanding of my invention, I show a fragment 10 of an automobile radiatorl having a filling neck 11 and over which tits a flange cover 12. A.As is usual with radiator cap covers, an ornament 13 which, for the purpose gitudinal axis of the of illustration, is shown as being in the form ofa vane, isvprovided on the cover and which 1t 1s desired to maintain in line with the lon;

automobile when the cover 1s secured in place.v i

Fitting within the neck 11 is a bushing 14 which is provided with a plurality of downwardl inclined slots 16 which open at the top o the bushing and which are provided with slightly upturned .ends 17. Fitting within the cover 12 is a plate 18 havin a plurality of arcuate slots 1 9 therein t rough which screws 21 extend for securing the plate to the cover. The slots 19 provide means whereby the plate may be adjusted angularly with respect to the cover.

Carried bythe vplate 18 is a center post 22 and guide pins 23 and 24. A spider 26, provided with a central opening'27, fits over the post 22 and is also provided with smaller `openings 28 and 29 fitting over the ide in's 23 and 24. The spider 26 is hel in ace by means of a spring 31 which surroun the post y22 and bears against the spider. Its other end bears a ainst an abutment 32 which is held in place ya .screw 33 whichv enters a threaded opening 34 in the post 22. The i screw 33 may be advanced or, retarded in the opening 34and the tension of the spring 31 thereby adjusted.

. Formed on the spider 26 are a plurality of down-turned arms 36 through which ass radially extending `pins 37 and carriedp by the pins 37 are small rollers 38. The spacing of the rollers l38 around the spider 26 corresponds to the spacing of the slots 16 in the neck 14 so that when it is desired `to secure the cover in. place on the radiator it is only necessary t'o enter the rollers in the slots 16, and give the cover a partial turn until the rollers enter the upturned ends 17 of the slots 16. W hen thus in place, the spring 31 holds the rollers in firm engagement with the slots and prevents the cover from coming llso it may-be done b'y loosening the screws 21 and rotating the plate 18 the necessary amount.

"In order that the cover may not be dropped and lost when removed, I provide a chain 39 i', which is secured to the'screw 33 and to the i m 14 and late 18 and that the fastenin means shown oes not have to be especial-ly esigned for each size of cover. It will accordingly v be apparent that I have devised an angularly i adjustable fastening means for radiator covers 15 which is simple of design and of operation and which is readily interchangeable with different sizes of covers.

While I have shown by invention in but one form, it will be obvious to those skilled in tlhe art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit thereof and I desire therefore that only such limitations shall be placed thereupon as are imposed by the prior g5 art or as are specifically set forth in the appended claims.

.WhatIclaimis:

1. In a fastener for container covers, a plu`- ralit of camisurfaced fastening elements carried y the container, a spider carried by the cover,'otlier fastening elements carried by the spider for cooperation with the fastening elements carried b the container, and 'means for angularly a justing the spider with reas spect tothe cover.

2. In a fastener for container covers, a neck on the container and carrying inclined fastening elements, a springpressed s ider carried by the cover, projections carried y the spider ments carried by the neck, and means for anlarly adjusting the spider with respetto t e cover.

3. 4The combination with a container having a circular walled openin therein and a fianged cover fitting over tie wall, of a plurality of fastening elements inclined tothe axis of the walled o ening and positioned around said wall, a spi er carried by the cover, means for angularly adjusting the s ider with respect to the cover, a spring for iasying the spider toward the cover, and radially pro'ectin fastening means ,carried by spi er an adapted to coact with the fastening elements.

4. In a fastening meansfor a container covv er, said container havin a circular walled opening, and said cover eing flanged to fit .65, with respect to the cover, and radial proje` over the circular wall, a bushing fitting with- `for angular y adjusting the spider with reand adapted to coact with the fastening elethe tions carried by the spider and adapted to enter the slots to secure the cover in place.

5. In a fastening means for a container cover, said container havin a circular walled opening and said cover being fianged to tit in the walled o ening and having provided therein aplurality of slots inclined to the axis of the bushing and opening at the top of the bushing, a s ider secured to the cover, means spect to the cover, radial rojections carried by the spider and ada ted) to enter the slots to secure the cover in p ace, and s ring means for holding the rejections in rm engagement with the wa ls of the slots.

` 6. In a radiator cover-fastening means, said radiator having a circular neck, a bushing fitting '.vithin the neck and having a plurality of inclined slots opening upwardly, a plate having a lurality of arcuate slots there- 1n, screws for olding the plate to the cover and passing through the slots, a spider yieldingly supported by the plate, and radial projections onthe spider for fitting in the inclined slots.
